Before you connect
Questions about UserStack.
The practical details behind the request, access and result.
What does UserStack User-Agent Lookup do?
It takes messy browser strings and turns them into clear info about what device, browser, and OS a visitor is using.
Can it tell the difference between a bot and a human?
Yes, it identifies search engine crawlers and bots with high accuracy so you can filter them out of your data.
How does it help with web development?
It helps you debug browser-specific bugs by quickly identifying the exact software version a client is running.
Can I use it to see what phones my visitors have?
Yes, it can identify specific mobile brands and models, which helps you optimize for the most popular devices.
Does it work for all browsers?
It parses a wide range of User-Agent strings, covering all major desktop and mobile browsers.
How do I get my access key?
You can get your UserStack Access Key directly from their website to connect this Connector to your agent.
Can I identify if a user is on an iPhone?
Yes! Use the detect_user_agent capability. The response will include the device brand ('Apple') and the specific model or type if available in the UA string.
Does this server detect search engine bots?
Yes. The underlying API identifies known crawlers like Googlebot or Bingbot. The agent will explicitly state if the detected agent is a crawler.
Can I parse multiple User-Agents at once?
Currently, the detect_user_agent capability processes one string per call. You can ask your AI agent to perform sequential checks for a list of strings.
One connection away
Give your agent a direct line to UserStack.
Connect UserStack once. Keep it beside 6,100+ managed Connectors when the next task needs more.
